You can use addnode to add a specific IP. It is very strange that this is occurring..

Correction
Message
No block source available
I thought that was probably it. You might try quit it and restarting it. It is an odd message to see, but perhaps that will help. If not, there are other suggestions. ;-) |

Is that the exact message you are getting? Or is it perhaps "No block source available"?
Installed version o.10.0 and synched when it was released.
now last 5 days - get message no blocks available
Reason?

I'm thinking of setting up an e-commerce store selling books for bitcoins, but waiting for the six confirmations to minimize my risk of a double spend attack. Does anyone know of any charts out there that list average confirmation time for the six confirmations to occur? My wish list for these charts: two charts, one that shows average amount of time to get six confirmations without any transaction fee, and another to show average amount of time with a transaction fee.
My concern is that I'm okay with waiting a day or two for the confirmations, but with typical e-commerce being instantaneous, customers would likely be frustrated and leave and I'd get no sales if this is common.
There are two separate questions here: 1. Once mined, the average time for 6 confirmations is, by design, going to be around hour. That is adjusted every, roughly, two weeks by the change in difficultly. The variance is an issue here of course, but it should be within 1-2 hours to get that many confirmations. Again, that is once mined. 2. The other question is what is the average time to get 6 confirmations including the time between when the transaction is submitted and when it is first mined. That is dependent on a number of factors, including if a fee is paid, the priority of the transaction (which includes the size) etc. This would be the average time of one hour, plus the time waiting for the transaction to be mined. The statistics for how long it takes a transaction to be mined will vary as above. [Edit: e.g. this depends on the number of inputs, the number of bitcoins (e.g. if you are selling an antique book for 1000 Euro (4 BTC from one output), you will get a much faster confirmation than if it is 0.0004 BTC from 50 different outputs because of the priority. etc) ] A few other notes: a. if you are truly selling "books for bitcoins" (not ebooks or something electronic), you can afford to wait much longer since you will no doubt have many hours to confirm the transaction prior to shipping. Even if you waited a day to ship, that wouldn't be an issue. You can accept the order when submitted, and ship once the transaction confirms. b. If you require payments to include appropriate fees, you will get a much faster confirmation. And you can say something like "transactions that do not include fees do not ship until confirmed. Transactions that include fees ship much faster." Make sense? |

Thanks for that explanation and breaking it down so it's easy to understand.
At least only addresses with spent outputs through a web wallet are possibly at risk, so that's good for me as I keep very small amounts in those. Keep your cold storage cold and only keep a small amount in your hot/spending wallets.
yes mostly online wallets/service. but sadly not only online wallets. i saw many droid technologies with same issues. and most problematic is the clones of cryptocoins which use this old android wallet clones. i already warned developers but many don't understand whats not good. i recommend sandbox system for handling BTC and/or cold-storage (paper & CLEAN usb flash). example I have computer with my bitcoins and only can connect with self writed IR-module for datatranser of signed transactions. so only can go out via IR to my internet-connected computer. and this have script which accept IR data and make rest. all started with little adruino experiment i made with friend  people often don't understand that enviroment must be secure. encryption and passwords is useless when enviroment is not secure. example you have super secured computer with sandbox (VM) and bitcoins safed here. but hacker goes in your computer with worm/expl/trojan and then waits for you type in password or keys and then all is stolen.. so most important thing is secure computer good or make it offline(no network communication i.e. rj45, wifi) when it s for bitcoin. Can you say which droid wallets use it? Thanks for posting this. Most of my bitcoins are already on paper wallets from a clean Ubunutu system (not connected to internet, old printer not connected to internet, etc). But I still have to use a hot wallet sometimes to pay people. Perhaps referring to the bad rng on android from about 18 months ago: https://bitcoin.org/en/alert/2013-08-11-androidBut that page says it was fixed with the "current" updates as of 2013. And the OP is talking currently of 2015. This is true, but as below it was a reference to past issues. |

There are a number of solutions including increasing the block size and side chains which could be used to handle more transactions. I wonder if bitcointalk.org could handle even 1 search per second.  |

please bro send me the profile of Theymos i only want to get it changed for once.. don't want a new account otherwise my post count will be 0  Just do a quick search with the search button, and you will find him. This is also pretty far off topic for here - perhaps in the Meta section. https://bitcointalk.org/index.php?board=24.0:-) |

Laugh all you want at the wolves and their games, but wall street equals not only big money, but also acknowledgement and press like this little thing in the journal and this is what Bitcoin really needs. It's no longer just some internet money of nerds and junkies  This. As an agnostic tool, the more adoption the better. Wall Street brings big money and even a small percentage of that is a good thing. |

Nice to see progress. When they shut intrade down a solution like this was the next logical step.

That explains why they had the twelve month lockup that some people were questioning and calling a huge negative.

Wow. Yachting is one of the last places I'd expect to see Bitcoin mentioned, but that is quite cool!

I think numbers like this happen because some block explorers take "change" sent back to the same address in to account as another "receive" whilst others don't?
So any option to get correct value for blockexplorer.com ? It depends on what is "correct". As Newar said, if you count everything, you get one answer; if you count everything except change, you get another. Some people might think change shouldn't count since it really wasn't sent to an address, it just remained there; others might say it should count. One could look at the code and alter it, and verify that this is even the issue. :-) |

"One of the chief complains...".
And I stopped reading when the first sentence hadn't even been proofread. Just about every article on there seems to have problems.
Complain and Complaint are different words.

Should the penetration of the latest version become a problem, it can be dramatically improved with (semi) automatic updates of desktop clients and availability of (semi) official binaries for various *nix flavors.
Current desktop user's are either not aware they can/should update, or they are not certain the upgrade will not mess with their wallet and they don't bother to spend time to verify that. The majority of desktop users are to lazy to upgrade, unless there is serious functionality upgrade, they are aware of.
The majority of server administrators like to yum / apt-get update daily/weekly/monthly, but when it comes to compiling the code, it takes effort to read through release/upgrade notes, backup wallet, etc, so they don't do it as frequently.
Automatic updates seem unlikely as a bad idea and has been discussed. I think anything involved with Bitcoin core is covered. But if Debian/Ubuntu/red hat package managers do their package updates quickly, that helps. :-) Quote from: gmaxwell on September 13, 2013, 08:39:10 PM If the core developers start telling you that you need developer controlled automatic update you can assume that we've somehow been compromised. https://bitcointalk.org/index.php?topic=293824.0 |

Hi,
You can definitely connect to bitcoind/bitcoin-cli via the command line?
e.g.
bitcoin-cli getinfo
(I'm asking because I see the authentication errors)
That is the main question I'd have next. :-)
|
|
|
|
Sure. ;-) Hopefully it helps! |

It is my understanding that bitcoin wallets are created through a hash table with 64 bits of alphanumeric characters. What happens when all wallets are completely used up? What happens then? Just a curiosity question.
In all likelihood the universe will have ended thousands billions of years before anyone (or any group) could generate them all. And if they did in some alternate reality with different laws of physics, they'd just be reused. If it ever looked like it was a physical possibility, doubling the length would change that. |
